PATENT MACHINE FOR TRIMMING SOFT-METAL LININGS OF CAR-AXLE BEARINGS.

SPECIFICATION forming part of Letters Patent No. 396,652, dated January22, 1889.

Application filed August 13, 1888. Serial No. 282,(384 (No model.) I

To aZZ whom it 'nz/ay concern:

Be it known that I, TIMOTHY W. lETMAN, a citizen of the 'United States,rcsiding in the village of est Troy, in the connty ot' Albany and Stateof New York, have invcnted certain new and useful lm n'ovements inMachines for Trimning Soft-Metal Linings of Car-Axle Bearings, ot' whichthe following is a specifieation, reference being had to the accompanyindraw in My in vent-lon relates to machines it'or trimmin to a curve orbevel the end parts of the thin soft-metal linings ot' car-axlebearings, and especially to such machines as hold the car-axle hearing'upon a stationary bed, and in which the trinuning is accomplished bytheuse of a han d-lever carrying a trimming-blade and having a universaljoint at its fulcrum end.

The primary objeets ot' my invention are toprovide superior means forclamping and holding the car-axle bearings upon the stationary bed, forreadily clamping and holding on the bed ear-axle bearings of differentlengths, and for presenting the same for the action of the trimmingdevice. I attain these objects by the mechanism llustrated in theaforesaid drawings, in which Fignre 1 is a perspective view ot' the1nechanism as when clamping and holding a caraxle hearing for the actionot' the trimminglever. Fig. 2 is a plan of the same mechanism as itappears when open to release or to receive a car-axle hearing, which isindicated in this figure by dotted lines, the trimminglever being turnedto one side and mostly broken off. Fig. is a partial elevation andlongitndinal section ot' the same at the line z 2 in Fig. 2, as whenclamping and holding for the action of the trimming-lever a caraxlehearing, which is represented in this fi gure in longitudinal section bybroken lines. 4 is an isometrical representat-ion of the bed-plate ofthe mechanism. Fig. 5 is an isometrical drawing ot' the cam-lever whichoperates the clamps, of which isometrieal representations are presentedby Figs. (i, 7, and 8. Fig. 9 is an isometrical illustration of themovable stop at the forward end of the car-axle hearing in Figs. l and3. Fig. 10

shows in plan a modification of the camlever, and Fig. 11 indicates themanner of its connection with eorrespondingly-modified clamps.

Like letters reter to similar parts in the several figures.

The bed-plate A is securely mounted upon supports B on a base, B', so asto leave an open space im'nediately under and around that portion of thebed-plate upon which. the caraxle hearing Y is held for the action ofthe trimning-lever C, which has the two-edged trimming or shaving bladc(u The bed-plate has separated seats a a and recesses b b' b so that theback of the car axle hearing may rest firnly on said seats, whicheverend of the axle-bearing is placed to the front to be acted on by thetrimmer.

The bed-plate is furnished with an end stop, as D or D', for one end ofthe car-axle bearing to rest against, as indicated in Figs. l and 3, andhas, as shown in Fig. i, a lengthwise-slotted way, E, and two tmnsverseslotted ways, F F', in which fit, respeetively, the sliding end elamp,G, Fig. (i, and the sliding side clamps, H H', Figs. 7 and S, which havewebs d extending downward through the slotted ways, and top fianges, e,above and bottom fianges, f, below said ways, whereby the clamps are soengaged with the ways, as in Figs. 1, 2, and 3, that the clamp'cannotbedisplaced thereon nor detached therefrom except by sliding the clamps inthe lengthwise direction of their respective ways.

To provide cheap, eltectual, and durable means for easily andsimultaneously sliding the clamps G H H' either outward or inward alongthe slotted ways, and thereby' securely clamping and holding fast uponthe bed-plate a suitable car-aXle hearing, Y, or releasing the same, thehand-lever I is mounted under the bed-plate upon a suitablepivot-support, as at J, Fig. 3, so as to be 'freely turned to and frothereon by hand in a plane parallel or nearly parallel to the top faceof the bed-plate. The lever I also has a cam, as g, which fits in atransverse slot, 7 Fig. in the lower partof the end clamp, G, as in Fig.3, and the lever has cams g' g which likewise work in transverse slotsh' h in the lower parts of the clamps H H', respcctively. The cams ofthe level' I are so arranged and engaged with the clamps that by turningthe lever in one di-` rection, as indicated by the arrow y in Fig IOO 2,all the clanps will be simultaneously slid i inward, so as to securelyclanp and hold the car-aXle bearing endwise between the end stop D or D'and the end clamp, G, and sidewise between the side clanps, H H', andthat by turning the lever I in the opposite direction all the clampswill be siinultaneously slid outward to release the car-axle bearin gand receive another one.

As an equivalent for the raised cams on the lever I and the transverseSlots in the lower parts of the clamps, the lever may have the cams inthe form of slots, as shown in plan in Fig. 10 at g g" 9 and the clampseach have a downwardly-extending lug, as illustrated in side elevationat h in Fig. 11, to engage with the slot-cams of the lever, as shown inthe latter figure.

To provide means for readily clamping upon the bed-plate car-axlebearings of two decidedly different leng-ths, the bed-plate has thepermanently-fixed end stop D, and adjacent thereto has the verticalsockets 'i e', Fig. 4, in which the novable end stop, D', Fig. 9, fitsin Figs. 1, 2, and 3, and is engaged with a lever, j, which is pivotedat j' to the bedplate, and by which lever the movable stop can beeXtended above the face of the bedplate, as shown by full lines in Figs.1 and 3, so as to serve as the stop for the forward end of the shortercar-axle bearings, and can be depressed even with or below the face ofthe bed-plate, so that the fixed stop D shall serve as the stop for theforward end of the longer aXle-bearings.

By having in or through the heads of the clanps set-screws, as 7; inFig. 12, the clamps can be used, in connection with the stop D or D', toclamp and hold fast on the bed-plate car-axle boxes of many Variouslydifferent length and widths.

L is a stock which is mounted on a fixed support, M, upon and extendingabove the rear portion of the bed-plate, and has at its forward end asocket, in which works the fulcrum-ball Zof the trimming-lever. Thestock L is adjustable along a guideway, m, on the support M in thelengthwise direction of the bed-plate byscrew-bolts n, extending throughparts of said support and through slots o in the stock, to therebyadjust the trinming-lever C with its blade c in proper position inrespect to the forward end of whatever car-axle bearin g shall be heldon the bed-plate, and at various inclinations to the central lengthwiseline, a; a', Fg. 3, in the face of the car-axle hearing.

The trinming-lever C has handles c', which are grasped by the hands ofthe person using the trimmer, and thereby moved to and fro about andwith the ball Z as a universal fulcrum-in the proper curved courses, andwith suitable Varying downward and lateral pressure to cause the blade cto properly shave or trim off the superfinous end portion of thesoft-metal lining of the car-axle hearing clamped 'upon the bed-plate.

I claim as my inventionl. The bed-plate turnished with an end stop for acar-axle hearing and having the lengthwise and transverse slotted ways,combined with the sliding clainps extending through and engaging withsaid slotted ways, and the Operating-lever mounted under the bed-plateand having cams engaging with said clanps, snbstantially as described.

2. The bed-pla'te having the len gthwise and transverse slotted ways,the fixed end stop, D, and the vertical sockets z', adjacent to saidstop, the movable end stop, D', fitting in said sockets, and the leverj, pivoted to the bedplate and engaging with said movable stop, combinedwith the sliding clanps upon, extending through, and engaging with saidslotted ways, and the lever mounted under the bed-plate and having cainsengaging with said clanps, substantially as set forth.

The combination, with the bed-plate furnished with an end stop for acar-axle bearing and having the lengthwise and transverse slotted ways,the sliding clamps upon, extending through, and engaging with saidslotted ways, and the lever mounted under the bedplate and having cansengaging with said clamps, of the stock L, mounted upon and adjustablelengthwise along and above said bed-plate, and the hand-lever C, havingthe trimming-blade and connected to said stock by a ball-anl-socketjoint, as set forth.

In testimony whereof I hereunto set my hand, in the presence of twosubscrbing witnesses, this lth day of August, 1888.

TIMOTHY XV. GETMAN.
